If you place the cursor over one of the buttons, you should see the 
following:
"drag to bullet or target" (tool tip message)
I'm sorry but this should have said "Drag to Accelerated Particle or 
Target Particle".
So what you do is drag one of the particles to the Accelerated Particle 
field.  The cursor will change when you move the cursor over the 
correct field.
Then you can click on the "Do It" button to calculate all the allowed 
interactions and display them in the field below the "View in Cloud 
Chamber" button.

You can not drag to that field as I explained above.
Once you do the above, you can select one of the lines (an interaction) 
in the display field and then click on the "View in Cloud Chamber" 
button to display the graphic of the interaction.

I'll clean this up a little and try to make the help clearer.
Thanks for the response,
